Special "drafting view" where can be represent element (as a dot) and add tag information. Around the dot can be draw 2D scheme.

In the special drafting view there could be selected any instance element from the dropdown list and drag the dot on a drafting view. The dot represents 3D object, what is possible to TAG and retrive information from 3D object. Around the dot, I can draw any 2D lines, which would be 2D scheme.

NB! It is like a legend, but in the special drafting view, where instance 3D object are represented as a dot. 

What problem it will solve for you?

I could make  electrical 2D schemes custom panel boards in drafting view which would retrive information from model.

For now in Revit there is no connection between ordinary 2D drafting view and 3D model. If I change 3D object (for example id. 123) parameters information in the model, then in the ordinary drafting view on a 2D scheme the  2D element (id.123) with parameter information would be with the old data.
